poor mileage, can't hear turbo.......
I have a 95 f350, 7.3, auto, crewcab, with extended chassis and a Hodges 19foot car hauler bed installed, with 103,000 miles.
I have a very slight trmble in engine at idle, with a vehicle on the truck and pulling a 18' loaded trailer I get 6.5 MPG. I was getting 10.7 MPG with the same load. I also noticed a slight loss in power and I don't hear the turbo spooling up. No smoke. Any help is better than no help.
I'm heading to church and I'll check back this evening to see what answers I have.
